Breandan Vallance, 17, won the international Speedcubing competition after beating off more than 400 rivals in Germany.
The student, from Beith in Ayrshire, triumphed in the traditional 3x3x3 Cube competition with an average "solve time" of 10.74 seconds and takes home 5,000 Euros (£4,700) in prize money.
"This year’s Championship has been a fabulous occasion - and enormous fun for the many hundreds of spectators who attended," said David Hedley Jones, Senior Vice President of Rubik Brand.
"It proves that, in the iconic Rubik’s puzzle, we have a phenomenal brand that has fantastic, never-ending potential."
The fastest "single solve" recorded at this year’s championship was by Piti Pichedpan, from Thailand, with a time of 8.84 seconds.
Contestants also entered events to solve the puzzle one-handed, with their feet, and blindfolded.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
